Product Overview
Silk Amino Acids are natural hydrolyzed silk fibroin protein extracts produced via controlled low-temperature enzymatic hydrolysis. Containing over 90% pure free amino acids & small molecular peptides, this fully water-soluble cosmetic raw material delivers instant moisturization, skin barrier repair, and hair smoothing conditioning effects. Controlled enzymatic hydrolysis (45–55°C) avoids over-degradation and unpleasant protein odor; pH 4.5–6.5 matches most personal care formula systems, compatible with transparent serums, shampoos, masks and leave-on creams. Available in pale yellow transparent liquid and spray-dried powder two forms, cosmetic-grade, compliant with global cosmetic safety standards, supporting bulk export and private label OEM customization for skincare, hair care and body care manufacturers worldwide.
Application of Silk Amino Acids
Silk amino acids feature small molecular peptides, complete water solubility and mild pH value, which perfectly match various cosmetic formula systems. It exerts moisturizing, film-forming, repairing and hair smoothing effects, widely applied in below finished personal care products:
- Facial Care Products
Facial essence, ampoule, moisturizing cream, gel mask, sheet mask, toner and leave-on facial spray. It penetrates the stratum corneum rapidly, replenishes amino acid nutrition, repairs damaged skin barrier, relieves dry tightness and softens rough skin texture.
- Hair Care Products
Shampoo, hair conditioner, hair mask, hair serum and anti-frizz hair spray. It adheres evenly to hair cuticles, locks moisture inside hair strands, reduces split ends and static frizz, restores natural glossy and silky touch.
- Body Care Products
Body lotion, body cream, transparent shower gel and hand cream. It forms a breathable moisturizing film on body skin to prevent dry peeling after bathing, delivering long-lasting non-sticky hydration.
- Transparent Clear Cosmetic Formulas
Clear serums, transparent shampoos and crystal shower gels. Fully water-soluble structure without sediment or turbidity, keeps finished products crystal clear while maintaining stable moisturizing performance.
- High-End Leave-On Cosmetics
All-day essence mist, sleeping mask and lightweight moisturizing emulsion. Low-molecular formula avoids heavy sticky residue, fits long-term contact with skin without clogging pores.

Manufacturing & Quality Control
Silk Protein Hydrolysis
Enzyme dosage and hydrolysis duration are controlled within 6–8 hours to stabilize peptide molecular distribution and reduce excessive protein breakdown.
Filtration & Purification
Multi-stage membrane filtration removes insoluble impurities and improves liquid clarity consistency.
Concentration Control
Vacuum concentration reduces thermal damage to amino acid activity during moisture removal.
Drying Parameters
Spray drying inlet temperature is controlled at 150–170°C to stabilize powder moisture and reduce discoloration.
Heavy Metal Monitoring
Raw materials and finished batches are tested for heavy metals to support cosmetic-grade application requirements.
Batch Verification
Each batch is tested for amino acid content, nitrogen, pH, moisture, appearance, and microbiological compliance before shipment.

FAQ
Q1: What cosmetic finished products can silk amino acids be added into?
A1: Widely applicable to facial serums, moisturizing creams, sheet masks, shampoos, hair conditioners, body lotion, transparent shower gel and leave-on essence sprays for daily personal care.
Q2: Will silk amino acids cause precipitation in transparent cosmetic formulas?
A2: No. Our raw material adopts multi-stage fine membrane filtration and full water-soluble molecular structure; it mixes evenly with aqueous transparent systems without residue or cloudiness.
Q3: Why is low-temperature enzymatic hydrolysis better than ordinary acid hydrolysis silk amino acids?
A3: 45–55°C mild enzyme reaction avoids violent protein breakdown, greatly reduces unpleasant residual odor, retains complete active amino acid structure and guarantees stable product color between batches.
Q4: Can silk amino acids be used for leave-on skincare essence and sprays?
A4: Fully suitable. Its low molecular weight peptides bring lightweight non-greasy texture, form thin breathable moisturizing film on skin without sticky residue, ideal for all-day leave-on skincare products.
Q5: Can I customize special microbial or heavy metal test standards for export?
A5: Yes. We control production and filling workshop cleanliness to adjust microbial indicators; heavy metal testing can follow EU, US or Asia regional import standards per customer demand.
Q6: What export documents can you provide for customs clearance?
A6: Standard export files include Certificate of Analysis (COA), Material Safety Data Sheet (MSDS), Technical Data Sheet (TDS), allergen statement, and third-party independent inspection reports; Halal/Kosher certification can be attached additionally.
Q7: What is the shelf life of liquid and powder silk amino acids after delivery?
A7: Unopened original sealed packaging liquid & powder grade share 24 months shelf life under cool, dry and shaded storage environment.
Q8: Is your silk amino acid raw material compliant with EU cosmetic ingredient regulations?
A8: Yes. Total heavy metal ≤10ppm, microbial control meets EU 1223/2009 cosmetic raw material standards, suitable for brands selling finished cosmetics in European markets.
